Description
Technical field
The present invention relates to expanded plastic technical field, relate in particular to the shock-resistant heat insulation expanded plastic of a kind of high rigidity.
Background technology
Expanded plastic, is obtained by plastic foamed moulding.Foaming is to make plastics produce the process of microvoid structure.Nearly all thermoset and thermoplastics can be made porous plastics, and conventional resin has polystyrene, urethane, polyvinyl chloride, polyethylene, urea formaldehyde, phenolic aldehyde etc.Existing expanded plastic is often used for heat insulation, but effect is unsatisfactory, and the impact resistance of expanded plastic and hardness are difficult to reach unified.
Summary of the invention
The technical problem that basic background technology exists, the present invention proposes the shock-resistant heat insulation expanded plastic of a kind of high rigidity, and impact resistance and hardness reach unified, and heat-proof quality is excellent, also has outstanding compression and tensile property.
The shock-resistant heat insulation expanded plastic of a kind of high rigidity that the present invention proposes, its raw material comprises by weight:
Preferably, in ABS resin, vinyl cyanide, divinyl and cinnamic weight ratio are 29-32:27-28:47-49.
Preferably, in EVA resin, the content of vinyl acetate between to for plastic is 12-16wt%.
Preferably, the shore hardness of polyethylene-octene copolymer elastomerics POE is 72-80HA.
Preferably, its raw material comprises by weight:
It is major ingredient that ABS resin, EVA resin, epoxy resin, resol are take in the present invention, makes the present invention have excellent hardness and the outstanding performance such as heat-resisting, shock-resistant, fire-retardant; Add diisononyl phthalate DINP, octyl epoxy stearate to mix with major ingredient, when improving system mobility, material is better disperseed, realized the comprehensive raising of heat-resisting effect and mechanical property, and octyl epoxy stearate is also as stablizer, with antioxidant RD, antioxidant 4010NA combined action, significantly improve oxidation resistance of the present invention, not hardening in life-time service process, do not rupture, without shrinking perk phenomenon, not affecting viscosity, extend work-ing life of the present invention; Coordinate and add polyethylene-octene copolymer elastomerics POE as toughner, by different particle diameters and different toughening mechanism, toughening effect is significantly strengthened, increasing substantially the stable on heating while, have and there is good processing characteristics and impact resistance; And nylon 66 fiber and glass fibre are used in conjunction with, significantly improved stretch-proof performance of the present invention, simultaneously with gas-phase silica, wollastonite powder, pyroxene powder, mica powder combined action, greatly improved wear resisting property of the present invention, and by the characteristic of silane coupling A-172, make inorganic raw material and form an integral body with major ingredient; Whipping agent K, overcritical nitrogen, supercritical co mix with major ingredient and mating reaction, make the bubble in the present invention even, and have reduced thermal conductivity, have improved heat-proof quality, have also greatly improved compression ability.
